Red Hat Bugzilla – Bug 7823
trouble mounting XENIX filesystem

Problem: mounting XENIX partition
I have been unable to mount my XENIX partition. I have an IDE HD with a
SCO XENIX 2.3.4 partition taking up the full disk (240MB).
If the XENIX HD is installed on the primary/master IDE it will boot and
run successfully. If a fsck is run on the filesystem there are no errors.
On my Linux system I have a primary/master HD partitioned with win98 (2GB)
and Linux (8GB) and a CD on the secondary/master and everything works fine.
All attempts to mount the XENIX HD (secondary/slave) in the Linux system
have been unsuccessful.
Linux boot does recognize the XENIX HD (on hdd) as shown below:
# dmesg | grep hd
ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:pio, hdb:pio
ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio
hda: WDC WD102BA, ATA DISK drive
hdc: 36X CD-ROM, ATAPI CDROM drive
hdd: QUANTUM LP240A GM240A01X, ATA DISK drive
hda: WDC WD102BA, 9779MB w/1961kB Cache, CHS=1246/255/63
hdd: QUANTUM LP240A GM240A01X, 234MB w/256kB Cache, CHS=723/13/51
hdc: ATAPI 24X CD-ROM drive, 128kB Cache
hda: hda1 hda2 < hda5 hda6 hda7 >
and fdisk recognizes the XENIX partition hdd4:
# fdisk -l /dev/hdd
Disk /dev/hdd: 13 heads, 51 sectors, 723 cylinders
Units = cylinders of 663 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hdd4 * 1 722 239317+ 2 XENIX root
XENIX is listed in the RedHat Linux 6.1 Reference Guide page 460
as a supported partiton type. if I understand correctly, XENIX
has been merged into the Sys V loadable module (sysv).
But the mount command generates the error below:
# mount -t sysv /dev/hdd4 /mnt/sysv
VFS: unable to read Xenix/SystemV/Coherent superblock on device 16:44
mount: wrong fs type, bad option, bad superblock on /dev/hdd4,
or too many mounted file systems
I spoke to Dave Cook at RedHat tech support, he was very knowledgeable
and we tried several things but to no avail. He suggested I enter
a bugzilla report which I am doing now. I hope you can help.
The mount command is correct, and mount seems to be doing the right thing.
Looks like a bug in sysv support in the kernel - reassigning.

I have the same, exact, problem. RH6.1 with Xenix 2.3.4,
same error message.
I am running ADM486-100, 64M RAM, FIC 486/PCI Motherboard.

Found this ancient bug in the Bugzilla cleanup, taking.
Is there an interest still? We are on release 7.2 now.
The last 6.x supported is 6.2.
I spoke with sysv maintainer Christoph Hellwig (hch),
and he is generally available. Closing the bug as stale,
reopen if there's an actual interest and if a current
release can reproduce the problem. Then I'll take it up
